Packet based retransmission system for DMB service and apparatus therefor

Abstract

Disclosed is a packet based retransmission apparatus for a digital multimedia broadcasting (DMB) terminal supporting DMB service. The apparatus and system includes a DMB receiver for receiving DMB data transmitted through a broadcasting transmission medium; and a DMB transport mode release unit for releasing a DMB transport mode in the DMB data received through the DMB receiver and outputting a Motion Picture Expert Group-2 (MPEG-2) transport stream (TS), a packet data converter for converting the MPEG-2 TS output from the DMB transport mode release unit into packet data with a predetermined format and a packet-based transmitter for transmitting the packet data provided from the packet data converter.

1 . A packet based retransmission apparatus for a Digital Multimedia Broadcasting (DMB) terminal supporting a DMB service, comprising: 
 a DMB receiver for receiving DMB data transmitted through a broadcasting transmission medium;    a DMB transport mode release unit for releasing a DMB transport mode in the DMB data received through the DMB receiver, and outputting corresponding data in a Motion Picture Expert Group-2 (MPEG-2) Transport Stream (TS);    a packet data converter for converting the MPEG-2 TS output from the DMB transport mode release unit into packet data with a predetermined format; and    a packet based transmitter for transmitting the packet data provided from the packet data converter.    
     
     
         2 . The packet based retransmission apparatus of  claim 1 , wherein the packet data converter converts the MPEG-2 TS into multi-protocol label switching (MPLS) packet data.  
     
     
         3 . The packet based transmission apparatus of  claim 1 , wherein the MPEG-2 TS includes data generated by demodulating the received DMB data into a stream, decoding the stream into an analog audio signal and an analog video signal, and multiplexing the at least one of analog audio signal and the analog video signal into multiplexed data.  
     
     
         4 . The packet based transmission apparatus of  claim 1 , wherein the MPEG-2 TS includes data existing before DMB data received through the broadcasting transmission medium is demodulated into a stream, decoded and output as at least one of an analog audio signal and an analog video signal.  
     
     
         5 . The packet based transmission apparatus of  claim 1 , wherein the packet based transmitter includes an ultra-wideband (UWB) device.  
     
     
         6 . A packet based retransmission system for a digital multimedia broadcasting (DMB) service, comprising: 
 a DMB broadcasting apparatus for configuring DMB data for DMB transmission using multimedia data created by a content provider;    a broadcasting delivery medium for delivering the DMB data transmitted from the DMB broadcasting apparatus;    a DMB packet data converter for receiving the DMB data transmitted through the broadcasting delivery medium and converting the received DMB data into packet data with a predetermined format; and    a packet network for transmitting the packet data provided from the DMB packet data converter to a plurality of user receiving devices.    
     
     
         7 . The packet based retransmission system of  claim 6 , wherein the packet data converter converts a Motion Picture Expert Group-2 (MPEG-2) Transport Stream (TS) into multi-protocol label switching (MPLS) packet data.  
     
     
         8 . The packet based transmission system of  claim 6 , wherein the packet network includes an MPLS network.
